` 4 claims. (ci. 285-31) My present invention relates to improvements in joints for connecting a body member having an aperture and a tubular member. While this invention is intended for general use, it is especially well adapted to connect a vent pipe jacket to a roof flashing of the type disclosed and fully described in my United States Letters Patent No. 1,279,572 wherein the flashing is adjustable to roofs of different pitch.

A roof flashing of the type disclosed in the above identified patent has an aperture for a vent pipev and it is an object of this invention to provide a novel joint for connecting a jacket for said pipe t the flashing, and which joint includes a relatively deep channel formed by upsetting the edge portion of the flashing surrounding the aperture.

In forming the channel I serrate the edge portion of the flashing that forms the bottom and inner side of the channel to remove surplus stock land thereby permit the folding of the inner side of the channel flat against'the jacket.

Another object of the invention is to incline the outer side of the channel so that when the inner end. portionof the jacketV is inserted into the channel it has a beveled fit therewith and forms a relatively tight joint between the jacket and the flashing. Y

Primarily, the members formed 'by serrating the hashing are positioned so that when the Ainner end portion of the jacket is telescoped into `the channel, they are engaged by said jacket and pressed outwardly so that said members lie flat y and tight against the jacket.

Solder is used to rigidly secure the jacket to the flashing and either a soldering iron or a torch may be used for melting the solder and flowing the same in the channel between its outer side and the jacket. When a torch is used in soldering the joint the heat therefrom, which is much more intense than the heat from a soldering iron, makes the solder flux sufficiently fluid so that part thereof will flow through the joint in the channel and around the members of the inner side of the channel and thereby secures said members to the jacket by means of a sweat joint.

To the above end, generally stated, the invention consists of the novel construction and arrangement of parts hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate one embodiment of the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. l is a plan view of a jroof flashing and jacket for a vent pipe having the invention embodied therein;

Fig. 2 is a side elevation of the same;

Fig. 3 is a fragmentary'view in section taken on the line 34-3 of Fig. l, on an enlargedscale;

Fig. 4 is a fragmentary detail view in section taken on the line lof Fig. 1, on an enlarged scale;

Fig. 5 is a plan View of a blank sheet of metal from which the adjustable roof iiashing is formed,

the folding lines being indicated by broken lines, and the first step in the process havingbeen performed wherein a central aperture is formed in the sheet for a vent pipe and said sheet serrated; i

Fig. 6 is a fragmentary view, on the same scale as Fig. 3, showing a further step in the process in which vthe annular bead has been pressed from the blank; l

Fig. '7 is a View corresponding to Fig. 6, but showing another step in the process in which the sheet and its serrated edge portion have been upset to form a channel surrounding the aper ture in the sheet;

Fig. 8 is a fragmentary View in elevation, looking at the pari; shown in Fig. 9 in the direction of the arrow marked thereon;

Fig. 9 is a fragmentary detail view, in section, taken on the line 9-9 of Fig. 8;

Fig. 10 is a fragmentary detail view looking at the parts shown in Fig. 7 in the direction of the arrow marked thereon, on an enlarged scale; and

Fig. l1 is a detailed view in section taken on the line H--H of Fig. 10 and further showing in section a fragment of the jacket positioned to be inserted into the channel of the improved joint.

The numeral l2 indicates an adjustable roof flashing having a pair of expansible and contractable gussets I3 which make said flashing adjustable for roofs of different pitch. This roof flashing i2 is fully described in the patent heretofore referred to. Said roof flashing is formed from a single sheet of metal A by folding the same on the broken lines as shown in Fig. 5, and is secured to a roof by nails, not shown, driven through positioning bosses illpressed from said sheet. A central annular aperture l5 is formed in the roof flashing l2 through which a vent pipe, not shown, extends.

A jacket I6, in the form of an annular pipe, surrounds the Vent pipe above the roof flashing I2 and is spaced to leave an air space between said jacket and vent pipe. The upper end portion of the jacket I6 may be folded over the upper end of the vent pipe and turned downwardly therein as shown in the patent heretofore referred to, or a cap of the type shown in my 2,347,836 i A i lower end engages the inclined side of the channel 23 and as the jacket I6 is pressed downwardly in said channel, a relatively tight joint is formed between the jacket I6 and the flashing I2.

While the jacket is thus held, solder 23 is fiuxed by heat from a soldering iron or a torch and flowed in the channel 23 between the bead I1 and the jacket I6 and lbuilt up around the jacket and the bead II to afford a baille that prevents rthe solder from flowing outwardly onto the flashing I2. By making the solder flux'sufliciently fluid part thereof will flow through the joint between the jacket I6 and the inner side of the Achannel 23 and around the members I9 and thereby form a sweat joint between said members and the jacket I6. From the above description nular upstanding bead I'I is'pressed from said sheet. The bead I 'I is concentric with the annular aperture thereof.

' At the time the aperture I5 is `cut in the sheet A, andY before said sheet vis folded to form the roof flashing, the edge portion of said sheet surrounding the aperture I5 is serrated asindicated at I8, to remove suii'icient stock in the sheet A to remove surplus stock and permit the same to be folded, aswill hereinafter appear. The serrated edge portion I8 of the sheet A affords cir` cumferentially and edgewise spaced members I9. As shown, the members I9 are formed by cutting and punching circumferentially spaced round holes 26 in the sheet. These holes 26 extend into the aperture I5 and thereby remove all of the stock between the members I9.

The next step in the process of forming the improved joint is to bend the sheet A just inside of the .bead II, as indicated at 2I, downwardly through the aperture I5 and thereby position the section 22 of the sheetA between the holes y20 and the bend 2| and the members I9 downwardly and inwardly inclined, as shown in Figs. 8 and 9. Continuing this step in the process, the members I9 are bent inwardly and upwardly into positions shown in Figs. 10 andpll to form a narrow and relatively deep annular channel 23 to receive the lower end portion ofthe jacket I6. Obviously, the section 22 of the sheet A forms the outer-side of the channel 23 which is downwardly and inwardly inclined and the members VI9 form the bottom of the inner side of said channel.

` I'he final step in the process is toinsert the lower end portion of the jacket I6 into the channel 23 and at which time the outer edge of its I5 and is spaced outwardly it is evident that the above described joint rigidlysecures the` jacket I6 to the flashing and at the same time the Work may be performed very quickly and efficiently. The improved joint gives the work a neat and finished appearance.

The drawings illustrate a commercial form of the invention, but it will .be understood that the same is capable of certain modifications as to details of construction, arrangement and combination of parts within the scope of the invention herein disclosed.

What I claim is: A l, l

1. The combinationwith a roof flashing and a vent pipe jacket, of a joint connecting said flashing and jacket, said flashing having an aperture and a channel surrounding the aperture and into which channel the lower end portion of the jacket is inserted, and solder rigidly securing the jacket in the channel, the inner side of the channel beingserrated, said channel being formed by bending a portion of the flashing surrounding the aperture downwardly and then folding the same upon'itself.

2. The structure defined in claim 1 further including an upstanding bead pressed from the flashing and surrounding the channel and affording a baffle for the solder. J

The structure defined in claim 1 in which the outer side of the channel is downwardly and inwardly inclined and engaged by the outer edge of the jacket at its lower end and further including an upstanding bead pressed from the flashing and affording a baffle for the solder.

4. The structure defined in claim 1 in which the serrated portion of the body member extends across the bottom of the channel.
